New Guinea impatiens plant named ‘Duemagsal’

ABSTRACT

A new and distinct cultivar of  Impatiens  plant named ‘Duemagsal’ characterized by its upright and outwardly spreading growth habit; mounded plant habit; freely branching habit; relatively vigorous growth habit; dark green-colored leaves; freely and early flowering habit; large light red-colored flowers; and good garden performance.

Botanical designation: Impatiens hawkeri.

Cultivar denomination: ‘DUEMAGSAL’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of NewGuinea Impatiens plant, botanically known as Impatiens hawkeri andhereinafter referred to by the name ‘Duemagsal’.

The new Impatiens plant is a product of a planned breeding programconducted by the Inventor in Rheinberg, Germany. The objective of thebreeding program is to create new vigorous and uniform New GuineaImpatiens plants with large and attractive flowers.

The new Impatiens plant originated from a cross-pollination made by theInventor in July, 2007 in Rheinberg, Germany of a proprietary selectionof Impatiens hawkeri identified as code number F-19-18-07, not patented,as the female, or seed, parent with a proprietary selection of Impatienshawkeri identified as code number F-16-01, not patented, as the male, orpollen, parent. The new Impatiens plant was discovered and selected bythe Inventor as a single flowering plant from within the progeny of thestated cross-pollination in a controlled greenhouse environment inRheinberg, Germany in May, 2010.

Asexual reproduction of the new Impatiens plant by terminal cuttings ina controlled greenhouse environment in Rheinberg, Germany since June,2010 has shown that the unique features of this new Impatiens plant arestable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Impatiens have not been observed under all possibleenvironmental conditions and cultural practices. The phenotype may varysomewhat with variations in environmental conditions such astemperature, daylight and light intensity without, however, any variancein genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Duemagsal’. These characteristics incombination distinguish ‘Duemagsal’ as a new and distinct Impatiensplant:

-   -   1. Upright and outwardly spreading growth habit; mounded plant        habit.    -   2. Freely branching habit.    -   3. Relatively vigorous growth habit.    -   4. Dark green-colored leaves.    -   5. Freely and early flowering habit.    -   6. Large light red-colored flowers.    -   7. Good garden performance.

Plants of the new Impatiens can be compared to plants of the femaleparent selection. Plants of the new Impatiens differ primarily fromplants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Impatiens are more vigorous than plants of        the female parent selection.    -   2. Plants of the new Impatiens and the female parent selection        differ in flower color.

Plants of the new Impatiens can be compared to plants of the male parentselection. Plants of the new Impatiens differ primarily from plants ofthe male parent selection in the following characteristics:

-   -   1. Plants of the new Impatiens are more vigorous than plants of        the male parent selection.    -   2. Plants of the new Impatiens have larger flowers than plants        of the male parent selection.

Plants of the new Impatiens can be compared to plants of New GuineaImpatiens ‘Fisimp Salm’ (U.S. Plant Pat. No. 19,173), not patented. Inside-by-side comparisons conducted in Rheinberg, Germany, plants of thenew Impatiens differed primarily from plants of ‘Fisimp Salm’ in thefollowing characteristics:

-   -   1. Plants of the new Impatiens were more vigorous than plants of        ‘Fisimp Salm’.    -   2. Plants of the new Impatiens had larger leaves than plants of        ‘Fisimp Salm’.    -   3. Plants of the new Impatiens had larger flowers than plants of        ‘Fisimp Salm’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearanceof the new Impatiens plant showing the colors as true as it isreasonably possible to obtain in colored reproductions of this type.Colors in the photograph may differ slightly from the color values citedin the detailed botanical description which accurately describe thecolors of the new Impatiens plant. The photograph comprises a sideperspective view of a typical flowering plant of ‘Duemagsal’ grown in acontainer.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations, measurementsand values describe plants grown in 10.5-cm containers during the summerin a glass-covered greenhouse in Rheinberg, Germany and under culturalpractices typically used in commercial New Guinea Impatiens production.During the production of the plants, night temperatures averaged 18° C.and light levels averaged 4,500 lux. Plants were pinched one time aboutthree weeks after planting and were 16 weeks old when the photograph anddescription were taken. In the following description, color referencesare made to The Royal Horticultural Society Colour Chart, 2001 Edition,except where general terms of ordinary dictionary significance are used.
